Definitions

the present invention relates to a self-propelled combine harvester, comprising a threshing device, a separating device, a cleaning device, which is followed by a suction fan arrangement with at least one housing, at least one inlet opening and at least one outlet opening, a chopping device and at least one distribution device for accepting and discharging a chopper passing through the chopping device Gutstrom.
the combine harvester comprises a threshing device, a separating device, a cleaning device, which is followed by a suction fan arrangement with at least one housing, at least one inlet opening and at least one outlet opening, a chopping device and at least one distribution device for accepting and discharging a crop flow passing through the chopping device.
the suction blower arrangement is designed as a cleaning blower of the cleaning device and serves to convey a material stream consisting of short grain, chaff and the like consisting essentially of non-grain components out of a machine housing of the combine harvester and to transfer it to a distribution device which distributes the material flow over a distribution width on the field soil .
the chopping device is used to shred the material stream essentially consisting of straw coming from the separating device.
the material flows fed to the distribution device are each accelerated by the chopping device and by the suction fan arrangement before they are mixed with one another in the distribution device before the distribution. This mixing of the different, accelerated crop flows can influence the quality of the distribution and the distribution width.
the invention has for its object to develop a self-propelled combine harvester of the type mentioned, which is characterized by an improved distribution of the crop flows transferred to the distribution device.
a self-propelled combine harvester comprising a threshing device, a separating device, a cleaning device, which is followed by a suction fan arrangement with at least one housing, at least one inlet opening and at least one outlet opening, a chopping device and at least one distribution device for receiving and discharging the chopping device continuous flow of material, proposed, wherein the at least one inlet opening of the suction blower arrangement faces the cleaning device and the at least one outlet opening of the suction blower arrangement is positioned below the chopping device, so that a transfer of an air and material flow sucked in by the suction blower arrangement through the at least one inlet opening to the distribution device in in a lower area of the distribution device, the distribution device in an upper area the material flow passing through the chopping device and in brings the air and material flow to the lower area.
An upper layer is formed in the upper area, which essentially consists of chopped material.
the air and material flow forms a lower layer, above which the upper layer flows essentially in parallel.
the flow of material coming from the chopping device is thereby supported and accelerated the air and material flow coming from the suction fan arrangement when it emerges from the distribution device.
This has the effect that the crop stream comminuted by the chopping device floats on the air and crop stream of the suction fan arrangement when it emerges from the distribution device, and thus a greater throwing distance or distribution width is achieved.
the suction fan arrangement generates one intensive airflow than a conventional pressure blower arranged in front of the cleaning device, so that a higher proportion of admixtures and dust can be removed from the combine.
At least one rotor can be arranged rotating about a horizontal axis in the at least one housing, the at least one housing having two conical housing sections arranged in mirror image, which are arranged coaxially to the horizontal axis.
the housing sections which are of conical disk shape at least in sections, surround the at least one rotor arranged to rotate about the horizontal axis.
the at least one inlet opening can be designed as an opening arranged coaxially to the horizontal axis in at least one of the housing sections and the at least one outlet opening can be designed as an opening that extends perpendicularly to a guide segment that bridges a region between the suction fan arrangement and the distribution device.
the air and material flow sucked in by the at least one rotor is essentially fed into the housing from the front, i.e. essentially parallel to the plane of sieves of the cleaning device.
the air and material flow is discharged through the at least one outlet opening, which is positioned such that there is an approximately tangential transition of the air and material flow from the at least one outlet opening into the downstream distribution device.
the guide segment can bridge a free section between the suction fan arrangement and the distribution device, in which the chopping device is positioned.
the flow of air and material flows over the surface of the guide segment and can thus transport chopped material further in the direction of the distribution device.
the at least one inlet opening can be delimited in each case by a guide section which extends in sections in the circumferential direction of the horizontal axis and tapers in the axial direction, the guide section is interrupted in sections on its side facing the cleaning device.
the guiding section serves to assume that the air and material flow coming from the direction of the cleaning device is deflected.
the arrangement of the guide section is selected such that the interruption in sections enables the air and material flow to be accepted from the front, ie essentially parallel to the plane of the screens of the cleaning device.
the taper of the respective guide section can cause a deflection of the intake air and material flow into the inlet opening of the housing.
the respective leading gate can limit the suction of air and material in sections. In particular, the suction can be limited on the side of the respective inlet opening which faces the distribution device.
cutting elements can be arranged on a shaft rotating about the horizontal axis in the region of the inlet opening.
the cutting elements can crush the non-grain components in the sucked-in air and material flow in a free cut.
the cutting elements can be designed as knives or cutting threads.
the cutting elements can be used to eliminate excess lengths in the straw which, coming from the threshing device and the separating device, reach the cleaning device. An increase in the degree of comminution of the cleaning outlet can be achieved. Leakage losses during the transition to the distribution device can also be reduced.
the cutting elements can be used to improve field hygiene by destroying weed seeds and lost grains. This results in a reduction in the use of spraying agents and less effort in tillage for weed control.
the shaft on which the cutting elements are arranged can also drive the at least one rotor.
baffle plates are arranged on the inside of the housing sections surrounding the rotor.
the baffle plates can up to be arranged in the region of the outlet opening.
the baffle plates can preferably be pivoted on the inside of the housing sections. At least the baffle plates in the area of the outlet opening can be removed in order to be able to prevent a build-up in critical harvesting conditions.
counter knives opposite the at least one cutting element can be arranged on the inside of the housing sections. This enables the degree of comminution of the suctioned cleaning outlet to be increased, which contributes to a further improvement in field hygiene.
the suction fan arrangement can be transferred from its operating position, in which the air and material flow provided by the suction fan arrangement is transferred to the distribution device, to a transport position, in which the suction fan arrangement is in a position inside the machine housing, by means of a lever arrangement is located below the separator.
the suction fan arrangement can be designed to be pivotable about a pivot axis.
the at least one outlet opening of the suction fan arrangement can preferably be formed on at least one channel segment, to which the guide segment adjoins.
a plurality of channel segments can preferably be arranged lying next to one another in a common, horizontal plane. Each channel segment can have an outlet opening.
the suction blower arrangement can suck air essentially through a suction area located in front of the cleaning device, at least one air guiding element being arranged in the suction area.
the at least one air guide element can serve to deflect a partial air flow in the direction of a grain conveyor screw arranged below the cleaning device.
the cleaned grain which has passed the cleaning device, is fed to a conveyor device which conveys the grain into a grain tank of the combine harvester.
the redirection of the partial air flow in the direction the auger causes a higher pressure on the auger by increasing the maximum pouring cone, which means that a higher grain recovery rate can be achieved. Grain trickling out at high throughputs can at least be minimized or avoided entirely.
the at least one air guide element can be designed as a guide plate and / or as louvre-like, in particular adjustable, slats.
the threshing device, the separating device, the cleaning device, the suction blower arrangement and the chopping device are surrounded by a machine housing, wherein at least in the area of the threshing device and the separating device, closure elements are arranged which serve to deflect the air flow sucked in by the suction blower arrangement inside the machine housing.
the air flow generated by the suction fan arrangement can be diverted by means of the closure elements in such a way that it specifically flows over or around critical assemblies in order to remove deposits.
the targeted deflection of the air flow can be used, for example, to remove deposits on the separating device designed as a separating rotor without additional work.
the closure elements can be controlled automatically. This would enable a cleaning program for the combine's working units.
a ventilated drop step can be formed between a return tray arranged below the separating device and a conveyor tray arranged below the threshing device.
the suction blower arrangement can suck in air through the stone trap arranged below the threshing device between the drop stage formed between the return floor and the conveyor floor. The additional flow ensures additional segregation of the crop stream coming from the return floor and discharges chaff to the rear from the combine.
At least one loss sensor embodied in the area of the at least one outlet opening of the suction fan arrangement can be arranged.
the at least one loss sensor can be designed as a head sensor.
the positioning of the suction blower arrangement designed as a cleaning blower downstream of the cleaning device has the advantage that loss grains discharged with the air flow or removed by the cleaning device are sucked in by the suction blower arrangement and pass through them.
At least one sensor element designed as a radar sensor can be arranged in the region of the at least one outlet opening of the suction fan arrangement.
the speed of the crop flow, in particular the chaff, can be determined by means of the radar sensor.
At least one sensor element designed as a baffle plate with a weighing cell can be arranged in the region of the at least one outlet opening of the suction fan arrangement.
the throughput can be determined in connection with the speed determination by the radar sensor.
the suction blower arrangement can preferably be set up to separate the chaff sucked in with the air flow and to transfer it to a transport vehicle.
the chaff can be applied directly to the transport vehicle by means of the air flow.

the material flow 34 coming from the chopping device 5 and essentially made of chopped straw is supported and accelerated by the air and material flow 17 coming from the suction blower arrangement 12 in the region of the guide segment 16.
the crop flow 34 coming from the chopping device 5 flows in an upper region of the distribution device 6 between the scattering baffles 19.
the air and material flow 17 flows below the material flow 34 coming from the chopping device 5 in a lower region of the distribution device 6 between the scattering baffles 19.
